No. 81 1. Specification To all whom it may concern:

Be it known that VVILLIAi/rl I. KAISER, a citizen ofthe United States of America, and a resident of the cityv of -Seattle, in the county of King and State of Washin ton, have invented certain new and useful improvements in Stoppers, of whichthe following is a speciication. L

My invention relatesl to improvements in stoppers'for sinks; and the primary object thereof is to provide an improvement of this .type which will be extremely simple of construction and coin aratively inexpensive to 'manufacture, and by its construction, aside from serving as a stopper, can be employed to remove any temporary obstruction in the outlet-pi e. v i l With t e above and other objects in view, described in the following, the invention conzosists of the parts, arrangement, and combinationjof parts referred to in the following, and

, claims.

In. the accompanying drawings, in which 'like numerals .of reference indicate like parts throughout the severai views, Figure-l is a view in top plan of my invention. Fig. 2 is a diametrical section thereof. Fig. 3 is a fragmentary view of a sink with my improve- 3o ment shown in position ovgi; the outlet thereof a flexible body 1, illustrated as being circu- 4 o lar in form and being formed on its un er face with a centrall -disposed boss or thickened extends through' the body 1' and the boss 2' portion 2 whic gives rigidity to the stopper, and, having its outer face convex, as shown in the drawings, will rest snu ly in the conc'aved perforated strainer 3, whic covers the outlet opening of the sink 4. l

Reference-numeral 5 indicates a bolt which v thereof, and onthis bolt are arran ed wash- 5o ers 6, which bear on o posite sic es of the stop er and are held t ereagainst by the hea 7 of the bolt and nut 8. The lower end of the bolt is Unthreaded, this yportion ofthe of Letters Patent;

:bolt being indicated by reference-numeral. 9 and adapted for insertion, preferably through, the central o ening or aperture ofthe strainer 3, whereby t e proper seating 'of the stopper is assured. The stopper is preferably formed To remove any temporary obstructionsover `the strainer 3, as heretofore state ,and sufficient water admitted into the sink to kee from the outlet-pipe 10, the stopper is laced raised and lowered, this .being done Without lifting the edges of the stopper from the sink,

and theforce of suction resulting from this action will readily clear the p If desired, a chain or other y tioncan be attached to ring 11 of bolt 5 to fa'- -cilitate the removal. of the stopper or in theA operation thereof during the removal of cbstructions in the outlet-pipe 10.

e efficient, I do not desire myself to be .understood as limiting the invention to that form alone. Y. i

Having thus described my invention, what While I have referred to the stopper as bey inici: circular formand have found the saine to 8o.

i e. ilexible co'nnec-A Iclaim as new, and desire tosecure byLetters v- Patent of the United States of America', is

1. A stopper of the type set forth consisting of a flexible body portion formed on one of its faces with a boss, and a bolt projecting through said boss, the portion of the bolt below said boss being unthreaded. A stopper ofthe type set forth having a iiexible body portion formed `on one of its Ifaces with a boss, a bolt projecting through said boss and being formed with a threaded portion, anda nut'on said threaded 1pprtion, the portion of the bolt below said t eaded portion being unthrealed',"substantially as and for the purpose specified.

A device ofthe type set viorth.fwhiclii serves as a combined stopper and means for Y removing obstructions from the outletipe of a sink or the like, consisting. of a disk, av-

ing a flexible outer portion, in combination I with a sink having an outlet, meansconnected to the central portion of the stopper for causing the same-to be alternately raisedand low- 92 @wem i i, E i l i the lower face of smid soppm, im* @he @miv pese speci'iied,
